HAY-ELEVATO R.

SPESIE'ICATION forming part of Letters Patent No. 339,496, dated April 6, 1886.

Application filed July B, 1895.

To @ZZ whom it may concern:

Be it known that I, Tnoiuns TEMPLE, a citizen of the United States, and a resident of Hud son, in the county of Lenawee and State of Michigan, have invented certain new and useful Improvements in Hay-Elevators; and I do hereby declare that the following is a full, clear, and exact description ofthe invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

r elevator arranged in its operative position,

one side of the box or casing in which the iree ends of the slings are detachably secured u being partially broken awayr to illustrate the construction and arrangement ofthe several parts. Fig. 2 is a side view of the slings in which the bundle of hay is secured and their adjacent parts, the sides of the box or casing in which the free ends of the slings are detachably secured being broken away to illustrate the construction and arrangement of the several parts. Fig. 3 is a detail view in perspective of one of the `coupling devices which connect the upper ends of the slings to the lower endsWof the draft or elevator ropes; and Figli is a detail view of the spring-clutch I.

rIhe same letters of reference indicate corresponding parts in all the gures.

Referring to the several parts by lett-er, A represents a supporting-rope, which is provided at its lower end with a suitable pulley, A', over which runs the draft or elevating rope, the rope A being of such a length, and being secured at its upper end to one of the rafters of the barn in which the hay is being stored at such a point, as to permit of the bundle of hay which is elevated in the slings being swung immediately over the mow, where it is released from the slings through the mechanism which will be hereinafter described.

B represents the single draft or hoisting Serial No. 170,983.

rope,vwhich passes over a suitable pulley, B3, secured at apoint a little above the hay-mow, and vthen over the pulley A', secured on the lower end of the supporting-rope A, that portion of the rope which passes over the pulley A' having connected to it the double draftrope B2, to the ends of which are attached the upper ends of the slings D D.

O indicates the box or Casin g through which the double draft-ropes pass, and in which the free ends of the slings D are detachably secured, the said casing having journaled in each end a pulley, C' C', under which the double draft-ropes run. Between these pulleys C' C' is centrally pivoted a key-lever, C2, the lower portion of which is bent at right angles to the main vertical portion, and the free extremity of this horizontal lower portion comes in close proximity to a stop or projection, c', formed transversely in the casing C, as shown, a spiral spring, C3, serving to hold the key normallyY in this closed position, with the extremity of the arm c in contact with the projection c'. An operating-cord, 0*, is secured at one end to the upper extremity of the key-lever C2, by means of which the said lever may be swung intoits open position, as shown in dotted linesin Fig. 2 ofthe drawings, for the purpose hereinafter specified.

To the lower ends of the double draft-rope B`Z are connected, by means of the coupling devices EE, (the construction of which will be 'hereinafter described,) the slings D D. These slings are formed of rope or other suitable material, and are adapted to be secured around the bundle of hay which it is desired to elevate from the wagon upon the hay-mow, each of the said slings being formed at its free end with a loop, D', as shown. A short baud, F, of suitable material is secured at one end in the casing C, and is provided at its free end with the link or ring F', adapted to it around the lower horizontal portion of the key-lever C2, when the latter is in its closed position. A short chain may be employed in place of the band F, when desirable.

To the lower end of the supporting-rope A, near the pulley A' of the same, is secured the upper end of an auxiliary rope, G, which passes over a pulley, G', which is secured at a point about in the same plane as the pulley ICO . elevated in a vertical line unt-il it reaches the pulley A on the lower end of the supportingrope A, when the spring-clutch is released or opened by pulling upon its cord I', and the bundle is permitted to swing toward and over the mow.

'Ihe coupling devices E E, which serve to connect the upper ends ofthe slings D to the ends of the double draft-rope, consist each of a link formed of two sections, E and El, the section E being formed with the shoulder F." and the projection or key E4, having at its extremity the enlargement E, while the section Ez is provided with the longitudinal aperture Fi, oval in cross-section and of such a size as to admit of the insertion of the oval head E5 of the key or projection E* when the y upper edges of the aperture, as shown, thereby t preventing the coupling from separating,

while at the same time it may be easily uufastened when desired. The upper edges of the section El at the upper end of the aperture E are slightly grooved transversely, at E8, to form a seat for the ends of the oval head E5, after the saine has been turned into its locked position. A rubber tension-plate or washer, Ff, is seated upon the shoulder E3 Aof the section E', and serves as a spring to hold the coupling in its locked position and prevents the sections from working apart or loose from one another, this rubber disk yielding slightly as the coupling passes under or through the pulleys C C in the box or casing C, as the bundle is being elevated, and thereby prevents any extra strain or friction between the couplings and the said pulleys.

Atension-spring, J, having its lower free en'd slightly curved, is secured to one side of the box or casing C, and to the side of the rack upon the hay-wagon is secured a cord, J, pro vided with a loop, J, at its free end, adapted to fit around the lower curved end of the tension-spring J, for the purpose which will be hereinafter fully described.

The operation of inyimproved hay-elevator is as follows: The elevator having been adjusted in the position shown in Fig. l of the drawings, the free ends of the slings D D are passed around the bundle olk1 hay, and the band F is then drawn through the loops on the said ends, the link or ring F on the end of the said band being then slipped over the horizontal lower portion of the lever-key C,

casing while the bundle is being elevated to.

the top of the hay-mow. The loop on the end ofthe cord J/ is then slipped over the lower curved end of the spri ng on theside the box or casing C, and the spring-clutch I is allowed to grasp theweight-rope G at such a point as to hold the supporting-rope A in a vertical position.` By applying the necessary power to the lower end of the single draft-rope B the bundle will be now elevated, the cord J serving to hold the box C stationary until the slings have tightened firmly around the bundle, when the free 'curved end of the spring J yields suiliciently to cause the loop on the end of the cord J to slip off, thereby releasing the box C after the bundle has been tightly bound by the slings, while if this device were notused the bundle of hay would not have sufficient weight to cause the slings to tighten around it, and there would be danger of its slipping loose and falling out of the slings. Vhen the bundle has been elevated until the box or casing C comes in contact withthe pulley A on the lower end of the supporting rope A,the spring-clutch I is released by pulling upon the cord I,when the draft-rope operates to swing the bundle to one side over the Y hay-mow, the rope G running through the pulley G to 'admit of this movement. Vhen the bundle is immediately over the mow, the operating-cord C" is pulled, thus opening or IOO drawing back the key-lever CL and releasing the end of the band F, which in turn frees the lower ends of the slings D D, thereby releasing the bundle of hay and allowing it to drop upon the mow in its appropriate position.

The weight H then operates to bring thebox or IIO It will be be seen that my improved elevator is simple in construction, being devoid of all complicated parts which are liable to break or get out of order, while at the same time it is very efficient in its operation.

I-Iaving thus described my invention, what I i' claim, and desire to secure by Letters Patent of the United States, is-
